IMPROVEMENT IN BASE-BURNING STOVES.

Therschedle referred to in these Letters Patent and raking part f the lame.

I, ZEBULON HUNT, of the city-of Hudson, in the county of Columbia and State ofNew York, have invented certain Improvements in the Construction o1 Goatstovesand Furnaces, of which the following is a specification.

Nat-ure and Objects of the Invention.

My invention consists in providing the exit or draught- -pipe with a chamber, having a diaphragm or curtainpartition separating it from the nre-chamber, and ex'- tending down inside the case of the stove a little llower than the bottom of the reservoir, so as to improve the draught, and, at the same time, prevent the coal in the reservoir from igniting also, in placing a cold-air register or ventilator at or very near the mouth or open bottom of this draught-pipe chamber, so as 'more perfectly to regulate and coutrolthe fire.

Description of the Accompanying Drawing.

Figure 1 is a transverse vertical section of my improved stove. 1`

Figure 2 is a perspective View of the same.

Figure 3 is a front view of the' curtain-plate detac-hed.

General Description.

' A is the exit or draught-pipe chamber, one side of which. opens through the case ofthe stove, but is divided oi or separated from the fire-chamber bythe curtain-plate B, which extends down in front of it so as to leave an-opening between the bottom of this plate and the case of the stove sufficient to accommodate the exit-draught.

Gis the reservoir or `magazine for coal to supply the re.

D is a cold-air register or ventilator placed at or directly under the mouth of chamber A. It will be seen, by a reference to the drawing, that the bottom of the reservoir is a little above the bottom of the curtain-plate B. This renders the'reservoir perfectly safe, so that there is no danger` of the coal in it becoming ignited even in a direct-draught stove; since, as soon as the draught reaches the top of the' coal in the irepot, it is attracted directly to the mouth of the chamber A and passes oi` into the exit-pipe, as shown by the darts in figs. 1 and 2.

When it is desired to dampen or reduce the lire cold.

air is admitted through register D insuch. quantity as may be desired. `'lhis register is located at or so near the mouth of chamber A that the cold air may be all lowed to enter it simultaneously with the hot ain-'and thus immediately and thoroughly to check the draught or to reduce and regulate it and the fire, as desired. This is found to be the most` effective and simple'arrangement yet devised to control and regulate the fire in coal-stoves and furnaces.

'lhe curtain-plate B, which forms the inner side of t draught-chamber A, is cast in a single separate piece, as represented by g. 3 of the drawing annexed, and bolted through flanges on its sides or edges to the body of the stove. Itsform is such as' to make it t and sit close to the inside of the case at top', but to stand or hang oti from it at bottom far enough to form an open'fiue or mouth for the draught and smoke to pass freely through it into chamber A, and thence into the pipe. The three cuter sides of this chamber are cast with the shell of the stove.

What I claim as my invention isl. The-diaphragm or curtai-plate, when employed substantially in the manner and for the purpose herein set forth. f

2.- The combination and arraiigement of plate B,

chamber A, and ventilator D, substantially as audfor the purpose set forth.
